A middle-class mentality seeks a comfortable, complacent existence. It wants to avoid the pain of constant hard work.

Of course, there’s nothing wrong with that attitude, but you aren’t going to become a millionaire from the comfort of your couch. If your goal is becoming successful beyond your wildest dreams, you'll need to face discomfort and uncertainty at times. You must get used to pushing yourself outside of your normal boundaries.

Start by doing five things every day that make you uncomfortable or even scare you a little. Build up your physical and psychological endurance. Being willing to endure a little temporary pain will help you build the mental fortitude necessary to see you through difficult times. It will help you embrace the difficult decisions that must be made if you’re going to turn a cautious life into something extraordinary.

While you push the boundaries on your mental and physical abilities, it’s also important to keep close tabs on your spending habits. Adopting a frugal mindset alone won’t earn you more money or make you rich, but learning to live modestly is an important part of achieving overall financial stability. You'll only sabotage yourself if you blow your wealth before you have the chance to accumulate it.

“A frugal mindset focuses on what you need, not just on what you want or what you think will make you happy,” says Adam Toren, founder of Young Entrepreneur and Biz Warriors, a small-business forum. Once you recognize that needless impulse purchases undermine your financial freedom, it changes your whole perspective on consumerism.

Take a few simple steps down the economical path: shop with a list, look for deals online before making a purchase and buy used items.

Get up close and personal with your money habits. Record how you spend every dollar. Do this for at least 30 days so you can get a clear picture of your spending habits. Then take the time to analyze your practices. What are you buying that you could reduce or eliminate completely?

Start by looking for obvious cuts -- the cable bill for channels you never watch, the subscription for a magazine you hardly ever read, that gym membership you only use once a month. Cut these ongoing expenses and move to an à la carte method: Pay only for what you need, when you need it.

Rich people don’t rely on one job to build their wealth. They're always working something on the side.

Think of this as a chance to monetize a hobby or area of interest.

Do you love photography? Have a talent for music, art, tutoring or coaching? You could turn any of these areas into a lucrative side hustle. And who knows? Maybe your side job could be the start of a whole new career and fruitful money-making venture.

Most millionaires follow a rule of thumb that can work for you, too: Invest at least 20 percent of your household income each year. In fact, author Ramit Sethi contends that most millionaires don’t measure the amount they make each year. In his New York Times bestseller "I Will Teach You to Be Rich," he explains these high earners are more concerned about how much they save and invest over time.

You don’t have to be wealthy to work toward the 20 percent goal. You just have to start making regular contributions to an investment account. Begin with your employer’s 401(k) plan and set up an IRA. Next, switch your “big bank” savings account to a high-interest savings account. You’ll go from earning negligible interest rates to accumulating something meaningful over time.

This tactic comes with a side benefit that's also a deterrent to overspending: You have to make a trip to the ATM or bank to withdraw money. Once it's gone, you'll know you're done shopping. Try taking out $100 and making it stretch over a week. You’ll see those mindless $20 purchases come to a halt pretty quickly.

11. Associate with successful people

They say you can judge a person by the company he or she keeps, but you also can gauge someone's potential in part by taking a look at the people he or she associates with. Our friends affect our worldview. Their ideas and life philosophies eventually meld with our own, and their ambitions and dreams can be a catalyst for our own aspirations and desires.

Consciousness is contagious. Exposure to other driven, resourceful and intelligent people will broaden your state of mind and expand your thinking. There's a reason rich and successful people often form tight cliques and gravitate toward one another. The wealthy understand these relationships create a kind of synergy. Start increasing the amount of time you spend with people who are richer and smarter than you. Some of their success might rub off!
